Heading home Tuesday and heading back to work Wednesday could be a little slick for Madison drivers and others in southern Wisconsin.

The National Weather Service said the biggest impact from the storm will be along Lake Michigan, with several inches of snow possible along with reduced visibility and scattered slippery spots, but light snow is also expected to spread across southern Wisconsin.

A winter weather advisory has been issued for counties from Marquette and Green Lake southeast to Racine and Kenosha but not Dane County, in effect from 5 p.m. Tuesday to 9 a.m. Wednesday.

In the far southern tier of Wisconsin counties, some patchy freezing drizzle or sleet is possible early Wednesday morning.

There are more chances for snow Friday, before frigid air and sunshine comes to town for the weekend.
